For the Lifecam Studio, my system gives: [33604.108093] usb 1-5: new high speed USB device number 4 using ehci_hcd [33604.276241] uvcvideo: Found UVC 1.00 device Microsoft® LifeCam Studio(TM) (045e:0772) [33604.334468] input: Microsoft® LifeCam Studio(TM) as /devices/pci0000:00/0000:00:12.2/usb1/1-5/1-5:1.0/input/input7 For the Lifecam Cinema, I get: [33729.476089] usb 1-5: new high speed USB device number 5 using ehci_hcd [33729.626964] uvcvideo: Found UVC 1.00 device Microsoft® LifeCam Cinema(TM) (045e:075d) [33729.633068] input: Microsoft® LifeCam Cinema(TM) as /devices/pci0000:00/0000:00:12.2/usb1/1-5/1-5:1.0/input/input8 On my system the button works for the Cinema but not for the Studio.
